| Abstract: | The paper introduces improvement and reinforcements of 3 categories of abutment structures,and makes non-linear finite element emulative simulation of chambering method and ring beam method for prestressed reinforced concrete with large-scale finite element software Analysys.Analysis gained that these two kinds of methods attain all effectively goal to reinforce gravity U-type abutment. |
